The owner of 5 Columbus Circle, a 21-story, 219,000 SF building is bringing the property back to its glory days, switching out the aluminum façade for cast stone. Five Columbus Circle was built in 1911 as the headquarters for the U.S. Rubber Company and was given landmark status in 2000.  While the owners reclaim the historic feel of the exterior, the interior is receiving mechanical upgrades and new double-hung window frames.
